Application filed April 17, 1912. Serial No; 691,303.

To all whom it may concern:

Be it known that I, FREDERIC E. BER- TRAND, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in InsoleReinforcing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for operating on insoles which are used in the manufacture of boots and shoes, and more particularly to machines for reinforcing What are known commercially as Gem insoles, best illustrated in the Hadaway Patent No. 614,860, November 29, 1898.

The present commercial machine for mak-- ing Gem insoles is provided with two movable formers operating upon opposite sides of the lip of an insole to form a bead or crimp in the reinforcing material and secure it to the insole. In that machine the movable outside former operates so far in ad- Vance of the vertical plane of the forward edge of the inside former that the reinforcing material is secured to the insole outside the lip, or against the outer face of the lip and feather, before the adjoin-ing material within the lip'is secured to the insole by the inside former. Consequently the inside former is obliged-to operate upon the reinforcing material,- to press it against the face of the sole into the angle between the face of the sole and the inner face of the lip and against the inner face of the lip, after-the adjoining material outside the lip has adhered to the feather. Considerable difficulty-- has been experienced in forcing the reinforcing material properly into the angle between the face of the insole and the inner face of the lip and against the inner face of the lip when the adjoining material outside the lip is thus held under tension. Diflicujlty has been eX- perienced also informing the bead or crimp in the reinforcing material and-securing it in placejat the toes of narrow toed insoles. This difficulty isdue to the fact that the space between the converging lips at the toe of a narrow toed insole is less than the length of feed. Consequently there is danger of the feed advancing the insole to a position with its lip beneath the inside former as the point of operation of .the former is transferred around the narrow toe. Under such a condition the former is brought down on the lip instead'of inside the lip and imperfect work results.

The principal object of the present inven-v tion is to produce a machine for reinforcing Gem insoles which will perform the rein forcing operation in a more efficient manner than heretofore.

To the accomplishment of this objecta feature of the invention contemplates the provision, in a machine for reinforcing insoles, of a work support, anda plurality of oppositely disposed means operatingat op-, posit e sides of the lip of an insole mounted on the support to form a bead or crimp in the reinforcing material and secure it to the insole, the means for securing the material to the insole within the lip being arranged to operate in advance, in the cycle of opera- 1 tions of the machine, of the means for securing the material to the insole outside the lip and to thereafter hold the material within the lip from displacement, under the tension exerted thereon by the operation of the last named means. This arrangement, while enabling the reinforcing means to cooperate to form the head or crimp in the reinforcing material and, secure it to the insole, permits the means inside the lip to pull the material down into the angle betweenthe face of the insole and the inner face of the lip while the reinforcing material outside thezlip is loose and free from tension. It alsoconstrains the outside former to gather the reinforcing material from the free marginal'portion 'of the f Patented Mar. 6, 1 917.

they both operate on the same transverse strip of reinforcing fabric throughout any one cycle of operations of the machine. Different conditions require a different degree of over-lap of the formers and provision is, therefore, made for varying their over-lapping relation.

Another feature of the invention contemplates the provision in a machine for reinforcing insoles provided with a work support and a pressing device, of means for actuating the pressing device to press the reinforcing material a plurality of times against the same portion of an insole mounted on the work support. The invention contemplates actuating and mounting the pressing device so that it may press the reinforcing material a pl u 'ality of times against the same portion of the insoles in any manner found desirable or expedient, but in order that the provision of a pressing device for pressing the reinforcing material a pin ality of times against the same portion of the insole may not interfere with the rapidity of operation of the step-by-step feed, with which machines for reinforcing insoles are usually provided, the pressing device is preferably controlled by the feed mechanism and is actuated to press the reinforcing material against the same portion of the sole both before and after a feeding step. The feeding means and the pressing device are thus vibrated in unison. A

The invention also contemplates the pro vision, in a machine for reinforcing insoles provided with a work support, means for feeding an insole mounted on the support and a pressing device, of means permitting the device to yield laterally if the length of the feed stroke causes it to engage th lip of the insole. his construction permits the point of operation of the pressing device to be transferred around the toe of a narrow toed insole between the converging lips without injury thereto and insures that the reinforcing material will be forced down into the angle between the face of the insole and the inner face of the lip at the toe of the insole as effectively .as at the substantially straight portions of the insole.

In addition to the features of the invention above referred to, other features of the invention consist in certain devices, combinations and arrangements of parts fully set forth hereinafter, the advantages of which will be readily understood by those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawings illustrating the preferred embodiment of the invention, in which,

. Figure 1 is a left side elevation of the up per portion of the machine;

Fig. 2 is a front elevation, the combined cam and hand wheel being removed;

Fig. 3 is a fragmentary plan showing the adjustment of the inside former;

Figs. 4 and 5 are diagrammatical views illustrating the relative position of the reinforcing and associated devices at various parts of the insole;

Fig. 6 is a vertical sectional elevation of the supporting devices for the inside former; and

Fig. 7 is a sectional plan on line Fig. 6.

In the embodiment of the invention illustrated in the drawings the reinforcing and associated devices comprise a rotary work support,.an under former for engaging the feather and lip beneath the reinforcing material, a vertically and horizontally moving former for pressing the material against the outer face of the lip and against the feather and for feeding the work, a 'fixed former for guiding the work and smootl'iing and press .ing the material upon the feather, an inside former for pressing the material against the face of the insole, down into the angle between the face of the insole and against the inner face of the lip, and a pair of cooperating cutters for trimming the excess mate rial substantially flush with the edge of the insole. The work support, under former, outside formers and cutters are constructed and arranged, except as hereinafter specifically pointed out, substantially as in the machine disclosed in Letters Patent of the United States No. 614,860 issued to the Gem Flexible Insole Company as the assignee of John B. Hadaway, November 29, 1898.

The work support 1 is vertically movable to permit the insertion and removal of the work and is intermittently rotated during the operation of the machine through a pawl and ratchet device 2 from the usual connections to a cam 3 mounted on the main driving shaft f. The under former 5 projects over the feather and the lip beneath the re inforcing material and is vertically movable with the work support to facilitate the insertion and removal of the work.

The outside formers comprise a movable former 6 and a fixed former 7 secured to the machine frame. The former 6 is adjustably secured to the lower end of a vertically reiprocating slide 8 mounted to slide in a guideway 9 (Fig. 2). The upper end of the slide 8 carries a roll 10 engaged by a groove formed in the face of a combined cam and handwheel 11. Through the connections de scribed the former 6 is vertically reciprocated toward and from the insole mounted on the work support 1. In order to impart a horizontal movement to the former 6 to feed the work toward the fixed former 7 the guideway 9 is forme in a horizontal slide llo 12 mounted to slide in a fixed horizontal slidewry l3 beneath the usual retaining plates 14:.

In the illustrated embodiment of the invention the reinforcing material is pressed against the face of the insole down into the angle between the face of the insole and the inner face of the lip, and against the inner face of the lip by an inside former or pressing device 15. As shown particularly in Fig. 6, the inside former consists of a substantially square foot 16 for pressing the reinforcing material against the face ofthe sole and with an inclined face 17 for pressing the materialagainst the inner face of the lip. The inside former is actuated during the operation of the machine first vertically to pres-sv the reinforcin material against the face of the insole and then inwardly to iron the reinforcing material down I into the angle between the face of the insole and the inner face of the lip, and to press the material against the innerface of the lip. These results are obtained by mounting the inside former in a vertical slide carried by an oscillating carrier. The inside former is adjustably carried, through a slot and bolt connection 18, by a circular plate 19 formed on the lower end of a vertical rod 20. This rod is loosely supported in a thimble 21 mounted in a carrier 22. The thimble is mounted in the carrier 22 to slide vertically therein but is held from rotation by a block 23 secured to the carrier 22 and arranged to engage a plane surface 24 formed on the thimble (Figs. 6 and 7). To permit the thimble to yield vertically in the carrier 22 a spring 25, coiled around a reduced portion of the thimble, is interposed between a shoulder 26 on the thimble and an adjusting nut 27 exteriorly' threaded to engage interior threads formed within the carrier 22. R0- tation of the nut 27 adjusts the tension of the spring 25, the adjustment being retainedby a lock nut 27 threaded on the nut and ar ranged to engage the top of the carrler. The carrier 22 is formed on the horizontal arm of a bell crank lever 29 (Figs. 1, 2 and 3) loosely mounted on a horizontal rod 30 carried by the machine frame; The vertical arm of the bell crank lever 29 carries a roll 31 engaged by a groove riphery of the cam 3.

Through the connections described the inside former is actuated during the operation of the machine first vertically from the dot ted line position a, to the dotted line position Z2, Fig. 6, to press the reinforcing material against the face of theinsole- The continued swinging of the bell crank lever about the rod 30 then moves the foot from the dotted line position b inwardly over the reinforcing material to the full line posi-: tion, Fig. 6. This movement ofthe foot 15 formed in the pe irons the reinforcing material into the angle between the face of the insole and the inner face. of the lip and finally presses the material against the inner face of the lip.

In order that the inside former 15 may operate inside the lip while the adjoining material outside the lip is free from tension and to hold the material secured inside the lip from displacement under the tension of the outside former,the position of the inside former, in the machine illustrated in the drawings, is such that it operates in advance of the outside former 6 in the cycle of operations of the machine and overlaps the movable outside'former (Figs. 2, 4 and 5). By arranging the inside former so that it operates in advance of the outside former, in

the cycle of operations of the machine, the

inside former performs its functions at a. time when the adjoining material outside the lip is loose, that is, not under tension, thus permitting an unhampered positioning of the material into the angle between the face of the sole and the inner face of the lip. The overlapping of the outside former by the inside former holds the material secured to the insole inside thelip from displacement at the point where tension is placed on the material when the outside former performs its function.

In order to counteract the tendency of the material to spring away from the anglebetween the face of the insoleand'the inner faceof the lip, after thereinforcing operation just described has been completed, the peripheral groove in the cam 3 is provided with a double throw so that the pressing device may press the same portion of the reinforcing material a plurality of times against the insole. To permit this operation, Without interfering in any way with the usual speed with which machines of this type are operated, the inside former 15 is'operatively connectedto the feed slide 12 and the timing is such that the inside former presses the' material against the sole both before and after a feeding step. To this end the slide 12 is extended toward the rear of the machine and is then bent and extended toward the left (Figs. 1, 2 and 3). The end of the extended slide 12 is provided with a slot 82 (Fig. 3) which embraces the shank 33 of a block 34 arranged" to engage a groove 35 formed in the hub-of the bell crank lever 29-.

Through the connections described the inside former is reciproc ated simultaneously with the outside former 6 and is actuated by the two throws'ofthe cam 3- to press the same portion of the material against the in v sole both before and after a feeding step.

The slot 32 permits the adjustment of the the slotted end of the slide 12 to the shank of the block 34.

Referring now to Figs. 4: to 7, it will be noted that the points of operation of the re inforcing devices are transferred around the forepart of an insolefrom substantially one end of the breast line to the other. It has been found in practice that the space between the converging lips at the toe of a narrow toed insole is insufficient to permit the proper reinforcement at this portion of the insoles by inside formers heretofore devised. In order to transfer the point of operation of the inside former 15 around the toe of a narrow toed insole ,without injury to the converging lips in such manner that it will secure the reinforcing material in place on this type of insole as effectively as on broad toed insoles, the inside former is so mounted as to flex in the line of feed. To this end the rod 20 carrying the inside former 15 is mounted for limited rotation in the thimble 21. The thimble carries a vertical pin 37 (Figs. 6 and 7) which works in an opening 38, of a diameter larger than the diameter of the pin, formed in the plate 19. The pin isnormally held against one wall of the opening 38 by a spring 39, coiled around the thimble, one end of which is anchored to the plate 19 and the other end of which is attached. to one of a series of holes 40 formed in acircular plate 41 on the thimble 21. By pivotally mounting the inside former 15 for yielding movement about an axis perpendicular to the plane of an insole mounted upon the support the inside former is per mitted to flex in a plane parallel to the plane of the insole if it contacts with one of the converging lips on the back stroke of the feed movement.

In order to relieve the plate 19 of the pressure of the spring 25, so that the yielding movement of the inside former upon contact with the lip may take place without danger of the plate 19 binding on the lower end of the thimble 21, the rod is constructed for a slight amount of axial play in the thimble 21. As shown in Fig. 6 the rod 20 is somewhat longer than the thimble 21 to permit the axial play, the amount of which may be adjusted by a washer 4E2 backed by the nuts 43.

In operating the machine, after an insole has been placed on the work table and the table has been raised to bring the insole 'into operating position, the first operation,

(the tools being in the relative positions shown in Fig. 4), is caused by the cam 3 which brings the inside former 16 down from the dotted line position a, (Fig. to the dotted line position 0. The tool in this position is held yieldingly, but firmly, on the insole by the spring 25. The continued downward movement of the former former.

supporting arm 29 causes the former to slide inward over the reinforcing material to the full line position of. Fig. 6, the pressure steadily increasing due to the increasing pressure of the spring 25. The material, by this operation, is forced firmly and securely intothe angle at the inside of the lip. Now the outside former and feed foot 6 descends and forces the material firmly into the angle at the outside of the lip and against the feather. Owing to the overlapping relation of the formers 6 and 16 the material is securely held inside the lip at the point where the outside former is operating and, therefore, no opportunity is afforded for stealing material from inside the lip, or loosening it, by reason of the tension applied to the material outside the lip. In

other words, the material being first secured inside the lip, the most important place, and being held in position opposite the action of the outside former, that former is constrained to gather its material from the free portion outside the lip and above the under This, as will readily be recognized by those skilled in the art, is an important improvement in the operation of this type of machine.

The movement of the feed slide (to the left viewing Fig. a) which now takes place, carries the formers 6 and 16 forward, together with the insole, the relation of the inside former to the portion of the reinforcing material just operated on remaining unchanged during this movement. completion of the forward feed stroke the second throw of the cam 8 causes a second operation of the inside former and thus the same portion of the material is twice pressed against the face of the insole and inner face of the lip. The feed slide then returns and the cycle of operations is repeated.

In operating on broad toed insoles the mounting of the inside former in a manner to permit it to flex transversely is not so important, but in operating on narrow and pointed toed insoles this action of the inside former materially improves the quality of the work produced. lVhile the feed stroke is short, in practice about of an inch, it is obvious that when reinforcing a pointed toe if the inside former is raised above the lip it will be moved on the return stroke of the feed, at times, above the lip and will, therefore, descend upon the lip instead of inside it. In the machines of the prior art the inside former, being unyielding transversely, must necessarily be raised above the lip on the return stroke of the feed as if it engaged the lip during this stroke the insole would be forced back, or the lip or former broken. The throw of the cam 3 is, therefore, designed so as to raise the inside former a distance less than the height of the lip so that on the back stroke ofthe feed it enga es the lip, but the spring 39 permits it to ex as shown in Fig. 5, if the lip is engaged before the completion of the back stroke, and

the former is thus held to its position within the lip however narrow the toe may be.

In this connection it will be understood that the lip of the insole referred to throughout the specification and claims may be any marginal rib or abutment however formed on the insole over which the reinforcing fabric is beaded or crimped. 1

It will be clear to those skilled in this class of machines, with the'general objects of the present invention in view, that changes may I means to move said outside former into pressing engagement with the reinforcing be made in the details of structure, the described and illustrated embodiment thereof vbeing intended as an exploitation of its-'uii derlying essentials, the features whereof are definitely stated in their true scope in the I I claims herewith.
